The Master Core rally is fought on a mobius-strip-shaped racecourse; Sonic pursues the retreating behemoth while ABIS hurls meteor storms and energy blasts into the track. The robot is also capable of initiating Gravity Drive, but Sonic can use this to boost forwards himself and smash into Master Core's rocky underside.

Six hits sees the robot being drawn into the black hole itself, destroying SCR-HD once and for all, as well as stopping the Lightless Black.
